Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a tailstock sleeve structure for CNC machine tools. Background Technology

[0002] CNC machine tools are commonly used machining equipment, mainly used for processing various workpieces. When machining long workpieces, the tailstock sleeve structure of the machine tool is an essential functional component. This structure mainly includes the tailstock body and the tailstock sleeve mounted on the tailstock.

[0003] Currently, when placing a workpiece inside the tailstock sleeve, the workpiece needs to be fixed. However, existing tailstock sleeves can usually only clamp and fix workpieces of fixed size and specifications, resulting in low applicability of the device. Furthermore, the tailstock sleeve and tailstock body are mostly fixedly installed, making it difficult to adjust the angle of the tailstock sleeve. When the workpiece needs to change the processing angle, the processing effect is not ideal. Therefore, there is an urgent need to design a tailstock sleeve structure for CNC machine tools. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a tailstock sleeve structure for CNC machine tools.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tailstock sleeve structure for a CNC machine tool, comprising:

[0007] Tailstock body;

[0008] The sleeve body is rotatably mounted on top of the tailstock body via an adjustment component. Two hollow fixing rings are symmetrically fixedly fitted on the surface of the sleeve body, and each hollow fixing ring is provided with four positioning components.

[0009] The positioning assembly includes a screw rotatably mounted inside a hollow retaining ring. A slider is threaded onto the surface of the screw. Two connecting rods are symmetrically fixedly mounted on the side of the slider near the sleeve body, and the connecting rods extend movably into the sleeve body. A clamping block is fixedly mounted on one end of the two connecting rods inside the sleeve body. A driven bevel gear is fixedly mounted on the surface of the screw. A driving bevel gear meshes with the outer side of the driven bevel gear, and the driving bevel gear is rotatably mounted inside the hollow retaining ring.

[0010] Multiple driven bevel gears located on the same side have a transmission bevel gear meshing with their outer sides, and the transmission bevel gear is movably mounted in a corresponding hollow fixed ring.

[0011] A drive assembly for driving the two active bevel gears to rotate.

[0012] Preferably, the drive assembly includes a dual-axis motor fixedly mounted on the surface of the sleeve body. Both drive ends of the dual-axis motor are fixedly mounted with drive shafts, and the two drive shafts respectively movably pass through two hollow fixing rings and are coaxially fixed with the corresponding active bevel gears.

[0013] Preferably, the adjustment assembly includes a fixed frame fixedly mounted on the surface of the tailstock body, a rotating frame rotatably mounted inside the fixed frame, and the other end of the rotating frame fixedly mounted on the surface of the sleeve body. A drive motor for driving the rotating frame to rotate is fixedly mounted on the surface of the fixed frame.

[0014] Preferably, the multiple clamping blocks located on the same side are arranged in a circular array around the center of the sleeve body.

[0015] Preferably, each of the driving bevel gears and the same-side transmission bevel gears are respectively placed on both sides of the same-side driven bevel gear.

[0016] Compared with existing technologies, the advantages of the tailstock sleeve structure for CNC machine tools provided by this utility model are as follows:

[0017] This invention uses a dual-axis motor to drive two active bevel gears, and then, under the transmission of the driven bevel gear and the transmission bevel gear, each screw can rotate synchronously, thereby driving each clamping block to move synchronously and changing the distance between the clamping blocks. This achieves the fixing effect on workpieces of different sizes and specifications, improving the adaptability of the device. At the same time, the angle of the workpiece can be adjusted by using the drive motor, improving the processing effect of the workpiece. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1 to 3 A tailstock sleeve structure for CNC machine tools, comprising:

[0024] Tailstock body 1; Sleeve body 2, which is rotatably mounted on top of tailstock body 1 via an adjustment assembly. The adjustment assembly includes a fixed frame 12 fixedly mounted on the surface of tailstock body 1, a rotating frame 13 rotatably mounted inside the fixed frame 12, and the other end of the rotating frame 13 fixedly mounted on the surface of sleeve body 2. A drive motor 14 for driving the rotating frame 13 to rotate is fixedly mounted on the surface of the fixed frame 12. Starting the drive motor 14 can control the rotation of sleeve body 2 through the rotating frame 13, thereby changing the angle of the workpiece fixed inside the sleeve body 2 and improving the processing effect on the workpiece.

[0025] Two hollow retaining rings 15 are symmetrically fixedly mounted on the surface of the sleeve body 2. Each hollow retaining ring 15 is provided with four positioning components. The positioning components include a screw 3 rotatably mounted in the hollow retaining ring 15. A slider 4 is threadedly connected to the surface of the screw 3. Two connecting rods 5 are symmetrically fixedly mounted on the side of the slider 4 near the sleeve body 2. The connecting rods 5 move through the sleeve body 2. A clamping block 6 is fixedly mounted on one end of the two connecting rods 5 inside the sleeve body 2. Multiple clamping blocks 6 located on the same side are arranged in a circumferential array around the center of the sleeve body 2. A driven bevel gear 7 is fixedly mounted on the surface of the screw 3. A driving bevel gear 9 meshes with the outer side of the driven bevel gear 7. The driving bevel gear 9 is rotatably mounted in the hollow retaining ring 15.

[0026] Multiple driven bevel gears 7 located on the same side mesh with a transmission bevel gear 8 on their outer sides. The transmission bevel gear 8 is movably installed in the corresponding hollow fixed ring 15. Each driving bevel gear 9 and the transmission bevel gear 8 on the same side are respectively placed on both sides of the driven bevel gear 7 on the same side to prevent motion interference between the three.

[0027] The drive assembly is used to drive the two active bevel gears 9 to rotate. The drive assembly includes a dual-axis motor 11 fixedly installed on the surface of the sleeve body 2. Both drive ends of the dual-axis motor 11 are fixedly installed with drive shafts 10, and the two drive shafts 10 respectively move through the two hollow fixing rings 15 and are coaxially fixed with the corresponding active bevel gears 9.

[0028] The working principle of this utility model is as follows:

[0029] In use, the workpiece is first inserted into the sleeve body 2. Then, the dual-axis motor 11 is started to control the two active bevel gears 9 to rotate synchronously through the two drive shafts 10. Then, the driven bevel gears 7 that are meshed with each other rotate synchronously. Subsequently, under the transmission of the corresponding transmission bevel gears 8, each driven bevel gear 7 can rotate synchronously. At this time, each screw 3 rotates synchronously. Finally, the slider 4 and the connecting rod 5 are used to drive each clamping block 6 to move towards the workpiece until it is pressed against the workpiece and fixed. By adjusting the distance between multiple clamping blocks 6, the fixing effect of workpieces of different sizes and specifications can be achieved, which improves the adaptability of the device.

[0030] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
